Abstract:
US researchers have shown for the first time that a 34nm long DNA strand can be used as a molecular wire to conduct electricity. In the future, DNA could be used in nanoscale electronic computers, they say.

Jacqueline Barton and colleagues at the California Institute of Technology in Pasadena have shown that a 34nm strand of DNA - made up of 100 base pairs - can conduct a low current of electricity without being damaged.
